Kai's verdictS-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
